Embodiment Construction

[0029] Further illustrate the present invention below in conjunction with accompanying drawing and specific embodiment:

[0030] A kind of breeding method of high-yielding, stable-yielding, blast-resistant rice of the present invention takes the breeding method of Zhendao 669, a new line of precocious and late japonica cultivated jointly by Zhenjiang Institute of Agricultural Sciences in the hilly area of ​​Jiangsu and Jiangsu Fengyuan Seed Industry Company, as an example, specifically The breeding steps are as follows:

[0031] 1) In 2009, Jurong, Jiangsu, the high-yielding variety Wu 2674 was used as the female parent, and 6 blast-resistant varieties or lines such as Zhendao 16 were used as the male parent to obtain the hybrid F 0 ;

[0032] 2) In 2010, Jurong, Jiangsu, according to the combination of regular hexagonal planting method to plant F 1 , specific reference figure 1 Shown, F 0 Seeds are planted in combination at the vertex of a single regular hexagon (1), and ...

Abstract

The invention discloses a high-yield, stable-yield and rice-blast-resistant breeding method of rice. The characteristic that distances between six vertexes and center of a regular hexagon are uniform is utilized, and a regular hexagon planting method is adopted to plant and breed experimental populations different in generation, so that single-plant selecting field experimental errors are reduced; a single plant of a highly-competitive strain at the center of the regular hexagon uniformly generates environmental resource stress, so that genotypes low in resource utilization rate are inhibited greatly, and selection of single plants high in resource utilization rate is facilitated. The highly-competitive strain has the advantage of high sensitivity to neck blast, so that prevailing and infection of physiological races of rice blast are facilitated, and inspection of an anti-infection mechanism of F2 separation single plants is increased. The breeding method organically combines stable yield, high yield and resistance and is high in suitable range, and rice varieties bred by the method have the advantages of high and stable yield and good comprehensive agronomic character and are suitable for various planting modes.

Description

technical field [0001] The invention relates to a plant breeding method, in particular to a high-yield, stable-yield, blast-resistant rice breeding method. Background technique [0002] Rice is the main food crop of our people. With the improvement of people's living standards and the continuous trend of increasing population and decreasing cultivated land, increasing rice production and increasing stable supply have been the key issues that my country's rice breeding has been working on for a long time. It is the most effective and economical way to increase rice yield by using excellent germplasm resources for high-yield and stable-yield breeding. [0003] Breeding is to cultivate the environment resources (temperature, light, water, fertilizer and CO 2 ) High-efficiency utilization or resistance to a certain limiting factor (or biotic stress) and an excellent population that exhibits high productivity. The ideal plant type is the model for the population to maximize th...
